Bilingual Czech STEM Expert (PhD) — AI Safety

About the role — We're hiring PhD-level scientists who are proficient bilingual speakers (English & Czech) to help make advanced AI models safer. You'll apply your scientific expertise to evaluate and strengthen how these models handle specialized technical topics in Czech. No prior AI/ML experience is required — we'll train you on the workflow. — What you'll do • Write expert-level prompts in Czech across specialized scientific topics. • Evaluate and annotate model responses for scientific accuracy, helpfulness, and appropriate handling of sensitive content. • Apply structured guidelines to classify prompts and conversations. — What we're looking for • A PhD in chemistry, biology, or a closely related field — ongoing or completed — with the depth to write prompts across chemical, biological, or radiological and nuclear subject areas. • Native or near-native fluency in Czech, plus business-level written English. • Deep familiarity with modern laboratory and computational techniques in your subfield. • Sound judgment around scientific safety and the responsible handling of dual-use information. — Nice to have • Based in the Czech Republic or the wider Eastern Europe region. This is a preference, not a requirement — applicants based elsewhere are welcome. • Radiological and nuclear coverage from a chemistry background is welcome — radiochemistry, nuclear chemistry, energetic materials, or radiation physics all qualify. • Demonstrated depth in a specific subfield rather than broad coverage — for example organic or inorganic synthesis, molecular biology, microbiology, virology, or genetics. • Research or coursework touching on chemical safety and security, biosafety and biosecurity, or hazardous-materials handling. • Experience reviewing, grading, or red-teaming technical content. — Project Timeline • Start date: Immediate
